Built from 18-8 stainless steel with a bright, uncoated finish, this screw resists corrosion in moderate-exposure environments. It carries a 4-40 UNC thread designation and measures 1-3\/8 inches in length under the head. The 3\/32-inch hex drive accepts a standard Allen wrench or hex key, making it suitable for confined or torque-sensitive assembly work across mechanical, electrical, and light industrial applications.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for use in low-load, fine-thread assemblies where a flush or recessed drive head is needed. Common applications include panel mounting, instrumentation enclosures, small machinery, and electronic equipment assembly. The 18-8 stainless steel construction makes it a practical choice in environments with incidental moisture exposure. Installers in HVAC controls, electrical panel fabrication, and light mechanical assembly commonly use this screw size for securing small components and brackets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread for fine-pitch, low-load fastening applications\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch length under head for moderate grip depth\u003c\/li\u003e\n\u003cli\u003e3\/32-inch hex socket drive compatible with standard Allen wrenches and hex keys\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating thickness to account for in tolerance-sensitive fits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw suitable for any application requiring a 4-40 thread pitch, 1-3\/8-inch underhead length, and a 3\/32-inch hex drive in stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove using a 3\/32-inch hex key or Allen wrench; do not use an undersized key, as this can round the socket. De-energize any electrical equipment before fastening or removing screws in panel or enclosure assemblies. Apply thread-locking compound only if specified by the equipment manufacturer, as stainless fasteners in stainless tapped holes can be prone to galling — consider anti-seize on fine threads if re-torquing is expected. Follow applicable mechanical codes and equipment manufacturer guidelines for torque requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R57001010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694264811826,"sku":"R57001010","price":787.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bbf22cf0b39ebfe1ceebd34142a8b62.jpg?v=1788322384","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001010-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
